Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a snow melting machine which collects snow accumulated in front of a house or a garage in a snowy area, a parking lot or the like and melts it in a short time.

[0002]

2. Description of the Related Art Conventionally, a technique related to a snow melting machine has been publicly known, for example, a technique described in Japanese Utility Model Laid-Open No. 3-122116. In this technology, a heating cylinder (furnace body) is arranged in a machine casing (snow melting tank) having a supply port provided above, and the outlet of the burner is faced in the heating cylinder, and snow is introduced from the supply port. The heat from the burner melted the snow and processed it.

[0003]

However, in the above-mentioned prior art, the heating cylinder is heated to a high temperature by the combustion heat of the burner and melts the introduced snow. However, as shown in FIG. 12, the heating cylinder has a circular cross section. Therefore, when the snow around the heating cylinder is melted, the upper half of the heating cylinder is melted and the snow is dropped from above, but the lower half of the heating cylinder is melted around but the snow is not. Since it falls downward, a space like the bridge phenomenon is created in the Z part, and the Z part is heated directly from the burner without being cooled, so that it becomes hot and deformed, which may hinder the snow melting work. Of.
Therefore, the present invention seeks to provide a furnace body in which this portion is also cooled.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, a cylindrical furnace body is horizontally installed inside the snow melting tank, the burner combustion part is fitted from one end of the furnace body, and hot air is jetted from a flame outlet hole formed in the side surface of the furnace body. Thus, in the snow melting machine for melting the snow put into the snow melting tank, the furnace body below the center of the cylindrical furnace body is provided with means for guiding the snow melting water into the furnace body. Alternatively, the furnace body is formed in a pipe shape with a skirt widening in a sectional view.

[0005]

[Operation] Next, the operation will be described. That is, when the burner B burns, a flame is sent into the furnace body 1 and hot air is jetted from the flame outlet holes 7 to melt the snow put into the snow melting tank 2 and the melted snow water is melted. 1 Guide plate 1 provided on the lower side surface
It is received by the gutter 13 or the gutter 13 and enters the inside of the furnace body 1 through the flame outlet hole 7 to suppress the temperature rise of the lower side surface of the furnace body 1. Alternatively, by making the lower part of the furnace body wide at the bottom, snow melting water falls along the slope and suppresses the temperature rise of the furnace body.

Embodiments of the present invention will now be described with reference to the drawings. 1 is a side sectional view of a snow melting machine of the present invention, FIG. 2 is a front sectional view showing a first embodiment of a furnace body, FIG. 3 is a front sectional view showing a second embodiment of a furnace body, and FIG. Similarly, FIG. 5 is a front sectional view showing a third embodiment of the furnace body, FIG. 6 is a partial side view thereof, and FIGS. 7 to 11 are front sectional views showing the fourth to eighth embodiments of the furnace body. It is a figure.

Referring to FIG. 1, the structure of the snow melting machine of this embodiment will be described. The snow melting tank 2 is buried in the ground, and the interior of the snow melting tank 2 is constituted by a burner chamber E and a snow melting chamber C. . A burner mounting plate 25 separates the burner chamber E and the snow melting chamber C from each other. The snow melting tank 2 is constructed such that the bottom surface is inclined toward the manhole 15 and the burner chamber E
Is set to a high position, and the snow melting room C is set to a low position. A mud pool chamber D is formed at the lowest position of the snow melting tank 2 with a mud pool separating plate 23 interposed therebetween. A mud chamber lid 4 is arranged on the mud chamber D, the mud chamber lid 4 is inclined so as to descend toward the furnace body 1, and snow is dropped on the mud chamber lid 4. Even so, the snow falls in the direction of the snowmelt water pool W.

A drainage port 3 for draining the water in the snowmelt water reservoir W is opened from the snowmelting chamber C to the manhole 15. The drainage port 3 is opened inside the mud chamber D, and the position of the lower end of the drainage port 3 coincides with the water surface of the snowmelt water pool W, but the water surface of the snowmelt water pool W is the furnace body 1 Is located above the lower end of the. Since the position of the lower end of the drainage port 3 is located higher than the position of the lower end of the furnace body 1 by the distance a, the lower part of the furnace body 1 is constantly flooded into the snowmelt water pool W during snow melting work. Therefore, the furnace body 1 is prevented from being deformed or perforated.

A non-combustion oil pan 8 is fixed inside the furnace body 1 at a position higher than the water surface of the snow melting water pool W formed by the drainage port 3, and the non-combustion oil pan 8 of the combustion tube 5 is fixed. It is fixed at a position from the tip portion to the cooling chamber shielding plate 6 in the terminal direction of the furnace body 1. A burner B is arranged in a burner chamber E that constitutes a part of the snow melting tank 2.
The burner B is fixed to the burner mounting plate 25, and the portion of the combustion section 21 is projectingly fitted inside the furnace body 1. On the upper part of the snow melting tank 2, there are provided opening / closing lids 19 and 20 that can be opened and closed in the longitudinal direction of the furnace body 1 to the left and right with respect to the snow loading direction. A snow introduction guide plate 9 can be attached so that snow does not escape to the side. Reference numeral 22 is a burner control panel, and 24 is a burner control box.

A cooling chamber shielding plate 6 is fixed inside the furnace body 1 on the side opposite to the burner B, and the cooling water chamber F isolated by the cooling chamber shielding plate 6 is a furnace body. It is configured integrally with 1. An upper surface of the cooling water chamber F is opened, and a part of the snow that is thrown in enters from the opening of the upper surface and melts inside the cooling water chamber F, so that the inside of the cooling water chamber F is always maintained. There will be snowmelt water in the area. In this state, even if the flame of the burner B collides with the portion of the cooling chamber shielding plate 6, the cooling chamber shielding plate 6 is not significantly deformed or the holes are not opened. Then, the furnace body 1 is supported by the support plate 11.
It is supported by 0 and is in a floating state.

The furnace body 1 has a cylindrical shape as shown in FIG. 2, and the flame outlet hole 7 extends from the upper surface to the side surface.
・ A large number of 7 ... are opened. And the flame outlet hole 7
Has a small hole 7a on the upper surface and a large hole 7a toward the side surface.
b, the guide plates 12, 12 of the present invention are protruded from the large hole 7b in the lower half of the side surface (below the horizontal line passing through the center) to the left and right of the outer side and spouted from the large hole 7b. The snowmelt water after being melted by the hot air flows through the guide plate 12 and flows into the furnace body 1 from the large hole 7b so that the temperature of the lower part of the furnace body 1 does not rise and deformation or the like does not occur.

Further, instead of the guide plate 12, FIG.
As in the second embodiment shown in FIG. 4, the gutters 13a and 13b are fixed along the large hole 7b in the front-back (axial center) direction, and the gutter 13 is formed.
It is also possible to configure so that the snow-melting water that has fallen on a.13b passes through the large hole 7b and flows into the furnace body 1. Further, instead of the guide plate 12, as in the third embodiment shown in FIGS. 5 and 6, the receiving portions 7c, 7c ... Are formed so as to project on the lower outer sides of the large holes 7b. Then, the water melted on the side surface of the furnace body 1 may be introduced into the large holes 7b. The receiving portions 7c, 7c ... Can be easily formed by internal drawing or the like.

As means for guiding the snowmelt water into the furnace body 1, the furnace body 1 is composed of a semi-cylindrical upper furnace body 1a and a slightly larger lower furnace body 1b as in the fourth embodiment shown in FIG. Configure
Or, cut it horizontally on the center line and spread the lower side to the left and right so that the water after being melted by the upper furnace body 1a falls down along the side surface and falls on the inner side surface of the lower furnace body 1b. It is also possible to suppress the temperature rise of the lower furnace body 1b.

It is also possible that the furnace body 1 is not cylindrical, but only the upper part of the furnace body 16 is cylindrical and the lower part is rectangular with a widened hem, as in the fifth embodiment shown in FIG. As in the sixth embodiment shown in FIG. 9, it is possible to make the lower part of the furnace body 16 ′ wide and the slope can be curved.
As in the seventh embodiment shown in FIG. 10 or the eighth embodiment shown in FIG. 11, the triangular furnace body 17 may be configured so that the lower portion thereof expands. After the snow melts, the snowmelt water flows down on the slope below the body to suppress the temperature rise of the furnace body.

Then, in the furnace body 1 (16.17),
The flame outlet hole 7 is not opened in the part that is flooded into the snowmelt water pool W, the hole for draining water is opened in the lower surface, and the burner for inserting the combustion part 21 in the side surface of the furnace body 1 on the burner B side. The insertion hole is opened, and the combustion cylinder 5 is fitted around the outer periphery of the portion where the combustion portion 21 is inserted.

With this structure, when snow is removed from the snow melting tank 2, the burner is ignited and the flame is ejected from the combustion section 21 to heat the furnace body 1, the upper part of the furnace body 1 is heated. The snow on it is immediately melted by the heat of the furnace body 1 and the hot air from the flame outlet holes 7, and the snow that is thrown into the side of the furnace body 1 is melted by the flame at the contact part of the furnace body 1, One after another, it falls to the portion of the snow melting water pool W below the snow melting chamber C, and when it falls, it enters the inside of the furnace body 1 through the flame outlet hole 7 or flows on the slope to cool the lower part of the furnace body 1. The temperature rise of the furnace body 1 is suppressed, and the snowmelt water is discharged from the drainage port 3 to the manhole 15 one after another.

[0017]

Since the present invention is constructed as described above, it has the following effects. In other words, the snowmelt water is also guided and cooled in the lower part of the furnace body, and the lower part of the furnace body becomes hot and deforms, causing the furnace body itself to be deformed and causing a positional shift, thereby lowering the snowmelt efficiency. Since it is no longer used, it is constantly cooled, which improves durability and reduces the level of maintenance.
